Used Super 77 to laminate the ribs to the back of some desk calendars I've saved. They are long enough that the ribs fit. Looks like some kind of chipboard about 1mm thick. Perfect for my use.
Spars cutting, folding and gluing, total of 12 spars to do, 6-per side. 3m 77 again before folding, and using the square wood dowels shown to be able to apply pressure to the spar. Three layer spar of Springhill 125# TAG cardstock.
Doing the really small spars first. Small in height x width they are the longest, they reach all the way to the tips.
Balsa wood Center Rib. This rib is located inside the aluminum ribs for the power skid. Decided to use 1/4" thick balsa wood to make it. Main wing spars will be inserted 1/8" on each side and glued.
Spar before cutting and one after scoring fold lines. Spar was cut out and then folded into the proper shape several times to get it to remember folds, makes it easier when gluing.
Square wood dowel helping with the applying pressure to the spar to get good glue set on all 4-sides.
More to follow, just getting started.
